I have found sin actual practice fthat these jackets prevent injury tothe molds both before and during the pouring operation,V

andiithusqthe output'ofa foundry can be increased-and there;A are lesslosses due to rejections. On account of the fact that the mold isjacketed I find that at least insome cases, a somewhat smaller mold fora given job may be used, thanlwhere- Vitis unsupported whichof itself isimportant for obviousyreasons.

'Inaccordance with' the provisions-of the patent statutes, I havev'described ,the prin ciple of-operationvcfmy invention, togetherwithth'e apparatus vwhich I now consider to represent 'the bestembodiment thereof, 4but I Vdesire to .have it. understood 'that theapparatus shown is only illustrative and that the invention may becarried out' by other means.

`IVliat I claim as new and desire to secure by "Letters Patent of theUnited StatesY is '1. A jacketY for a sand mold" having substantia'lly.vertical faces, said j aclet comprising-a rigid'frame which conforms inshape to and` is slightly smaller inplan than the mold to bejacketed,'the edge vsurfaces on one side of said'frame acting from the verticalfaces of the mold as cutters to shave off jtheeXcess sand as lit islpushed over the mold to its"final position.

aok'etffora mold comprising a rigid open-ended substantially rectangularboxlike "frame j having plane interior surfaces and cutting surfacesalong the lower edge and which isadapted to be pushed Adown overaysand-mold to confine the same, said cutting surfaces shaving off theexcess sand from the'facesof the mold as'thev fra-me is moved tolitsfinal; position.

4. Ajaclzet for a mold comprising end and side members which are unitedat their meetingfedges to form an open-ended substantially rectangularbox, the interior walls ofwhich are plane: surfaces, and which in planis slightly smaller than the mold, said members ,being provided rwithcutting surfaces along their lower edges to remove excess sand from' themoldfaceswhile being` moved to a final position.
